The flat sided of the handle and regardless of how the hanportion 18 may conveniently be of square 5o dle may be worn inuse. f cross section, and the hub 13 is provided with 10G an aperture of similar shape and size so that in placing the valve member in the housing 10, its smaller tapered portion 17 will readily pass through the aperture in the hub 18, to mount the handle 14 on the valve member. The clearance space in the housing for the hub 13. is provided with paraliel walls' perpendicular to the axis ot the valve nicmber, which are separated a slightly greater distance than the length ot the hub member axially ot the valve member, and in this manner the handle 14tis kept in place on the valve member, so that rotating the handle rotates the valve member. The tapered portion 1G is provided with a port 19 so extending through the valve member that when the port extends vertically, the passageway 11 uninterrupted and fluid may iiow freely through the passage "ay and when the valve member is turned through an angle ot substantially 900, the port 19 assumes a horizontal position completely interrupting flow through the passageway 11. The tapered portion 1 through port establishing tree iiuid tlow through the passageway 12 at the saine time that the port 19 establishes tree low through the passageway 11, and proportioned so that when the valve member is in a position interrupting liow through the passage *ay 11, tlow through the passageway 12 would be irt-errupted by he tapered portion 17, if the port 2O were the only port in the tapered portion 17, and it' the passageway 12 were the only passageway controlled by the portion 17. The port 20, however, has communieating` with it, a. branch port ot substantially the same cross section, as indicated at 20a, which extends outwardly in but one direction from the port 20. As indicated in Fig. 2, the housing' 10 is provided with a cross or branch passageway 12a, extending from the outer surface oi the hou sing and opening` into the passageway 12 in line with the oie the valve member, the outer end of the passageway 12al being threaded to receive a suitable connecting pipe, as indicated tor the passageway 12 in Fig. 1. As a result of the construction described for the tapered portion 1.7, with the valve member in the position indicated in Fig. 1, iiow through lower part oi the passageway 12 is interrupted. but at the same time fiow permitted through the upper` part of the passageway 12 and through the passageway 12a by the ports 2O and 200,. lVhen the handle 14 is moved to a position to establish free tlow through the passageway 11, the port 20 establish es free flow through the passageway 12 and flow through the passageway 12a is interrupted by the tapered portion 17.

The valve member is provided on its smaller end, with a4 washer 21 which. is held in place by a nut 22 and by a pin 23 extending through the nut and the threaded end of 7 is similarly provided with a the valve member. rlhe larger end oit the valve member is provided with a slotI 2t for cmir'cniently grinding the valve member to a true lit in its seats when desired. The bore ior the valve member is extended bevond tl're larger end of the latter, and the end ot th:l bore closed by a threaded plug between the inner face ot which and the larger ond ot the valve member, a. ,spring 2li is disposed to hold the valve member snugly against its seats at all times.

As pointed out, to change the flow relations controlled by the valve construction from one condition to the other, the handle 14 is turned through substantially 90o and 1 find it convenient to limit the movement of the handle in either direction by providing a lug 27 extending towards the handle, from the upper edge ot the bridge portion 15 so that the edge of the handle engages the lug when tlow through the passageway 11 is interrupted, and the hub 13 of the handle is provided with a projecting lug 28 engaging the lower edge o1 the bridge member 15 at 29, when the handle is turned to establish tree fiow through the passageway 11.

1n Fig. 4, 1 illustrate diagrammatically the application of my valve construction above described, to an automatic control system for controlling the operation of railway trains. 1n this connection, my valve construction is installed on the locomotives as a part of the control apparatus with which they are equipped, to give the leading locomotive control of the braking system of the train, and to deprive the trailing locomotive for the time, of such control, where two locomotives are used on the same train. Two engineers air valves E and E are shown as part of the equipment of the two locomotives, which have similar connections and are similarly controlled, so that such connections are illustrated only Jfor the engineers valve E. The valve E is supplied with air under pressure by pipe 30 from the air tank T of the locomotive, and this valve through its operation controls the air pressure in pipe 31 communicating with the train pipe 32 in the usual man ner. My cut out valve construction is shown diagrammatically at 10 and may either permit free flow through the pipe 31, under control of the valve E, or prevent i'low through the valve 10 and the pipe 31 regardless ot the position ot' the valve E, as desired. The control system diagrammatically illustrated, is of the type in which any suitable actuating devices along the right of way, cause current impulses to iiow at desired times through wires 33 to actuate control valves B and C, one of which may operate an audible signal, for example a whistle 34, and the other of which may supply air under pressure from the tank 10 through pipe 35, to an actuator mechanism A for operating the engineers valve E. Where two locomotives are used pipe 31, communication is established between on a train, if the valve E is on the trailing locomotive, it is desirable that the actuator mechanism A be supplied with air directly from the tank T, when the valve E is disabled, but that when said locomotive isthe leading locomotive or is used alone, the control of the actuator mechanism A be by the control valve C, that direct communication between the tank T and the actuator mechanism A be interrupted, and that the .valve E shall have full control of the braking system. To meet these requirements, the valve C is connected by pipe 86 with one end, for example the lower end, of the passageway 12, the upper end of which is connected by pipe 37 with the actuator mechanism A, and the passageway 12a is connected by pipe 38 directly withthe tank T. As a result of the connections described, when the cut out valve mechanism 10 is in a position interrupting flow through the pipe 31, the smaller tapered portion 17, by its ports 2() and 20a, establishes communication directly between the pipes 37 and 38, and prevents air flow through the pipe 36 regardless of the position of the control valve C;

also, when the valve mechanism 10 is in a position permitting free flow'tlirough the the pipes 36 and 37 and flow through the pipe 38 is prevented. For the latter condition of the valve 10, the actuator mechanism A is controlled to in turn control the operation of the engineers valve E, by the control Vvalve C. The control system described does not 1, constitute a part of my present invention and is not thereforel shown in all of its detail, as it is well known in the art and is presented diagramniatically to illustrate one use of my cut out valve construction. It will be understood that the other engineers valve E is connected and operated in the same manner described for the valve E. It will also be understood that my valve construction may be effectively used for any other purpose where it is desired to simultaneously control fluid flow through separate paths, and that the ports of the two portions of the valve meinber and the passageways controlled by the saine may have any desired relation to meet the requirements of any particular case.

While I have shown my invention in the particular embodiment above described, it will be understood that I do not limit myself to this exact construction as I may employ equivalents known to the art at the time of the filing of this application without departing from the scope of the appended claims.

That I claim is:

1. In a valve construction, the combination f. of a cast metal integral housing having two through passageways side by side for fluid flow, a tapered integral valve member crossing said passageways and having ports opening and closing said passageways by turning f movement of said valve member, and a handle carried by said valve member for turning it, said passageways having separated adjacent walls in substantially parallel relation, said valve member between said walls having a fiat sided conformation, and said handle having a hub portion fitting loosely between said adjacent walls and having an aperture fitting the flat sided portion of said valve member.v
